BACKGROUND Although patients with immunoglobulin light chain (AL) cardiac amyloidosis exhibit worse outcomes than those with transthyretin (TTR) cardiac amyloidosis, few data exist regarding the occurrence of cardiac events and the echocardiographic indices in endomyocardial biopsy (EMBx) proven amyloidosis. METHODS From November 2007 to October 2012, we(More)
OBJECTIVES This single-center study was performed to analyze the effect of an increased transvalvular gradient after the MitraClip (MC) (Abbott Laboratories, Abbott Park, Illinois) procedure on patient outcome during follow-up. BACKGROUND Percutaneous transcatheter repair of the mitral valve with the MC device has been established as a novel technique for(More)
BACKGROUND Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV(More)
BACKGROUND The aim of the study was to investigate mortality following transcatheter mitral valve repair with the MitraClip System (MC) (Abbott Vascular, Santa Clara, CA, USA) in patients with mitral regurgitation and moderate-to-severe symptomatic heart failure in comparison to mortality predicted by the Seattle Heart Failure Model (SHFM) and the heart(More)
BACKGROUND Very limited data exist on the outcomes of transcatheter aortic valve implantation (TAVI) since Japanese marketing approval of the first TAVI device.Methods and Results:The Kyoto University-related hospital Transcatheter Aortic Valve Implantation (K-TAVI) registry includes prospectively collected data from 6 participating hospitals in Japan. We(More)
As Japan has one of the most rapidly aging populations in the world, transcatheter aortic valve implantation (TAVI) is likely to be performed in increasing numbers of older people. There is little information on either the efficacy or the safety of TAVI in nonagenarians in Asia.From October 2013 to June 2015, 112 consecutive patients underwent TAVI with(More)
